  • Patent number: 6453957
    Abstract: A cutting attachment is adapted to be mounted onto a vehicle, such as a skid steer loader, and includes a frame that is generally “V” shaped with diverging walls and open in direction of travel. The diverging walls of the frame support upright shafts. Each of the shafts has a rotating disk on the lower end thereof that has a circular cutting edge. The disks are preferably co-planar and closely adjacent to each other along a center longitudinal axis of the frame, and are not powered. When the disks are moved against standing vegetation with stalks or trunks, they rotate and sever the vegetation. Additionally, a lift plate is provided on the trailing side of the disks so after severing the vegetation the lift plate lifts the trunks of trees or stalks or the like upwardly from the disks. The lift plate is inclined to tend to cause the trees to tilt outwardly. Support arms can be closed to hold the cut tree or other vegetation in the frame until the arms are released.
